Strickland House, Vaucluse, Heritage-listed house in Vaucluse, Sydney, Australia

Strickland House is a two-storey mansion with white walls and a dark brown tiled roof, built from 1830 to 1858 and designed by John Frederick Hilly. Its front has a projecting central section with a ground-floor portico supported by four white columns, above which sits a balcony with an ornate dark metal railing and a small red-framed window. Two tall chimneys rise from the roof, and the tall windows have dark red frames and multiple panes.

John Hosking, the second Mayor of Sydney, commissioned John Frederick Hilly to build the villa Carrara in 1856; an advertisement for contractors to erect its walls appeared in the Sydney Morning Herald on 15 April 1856. The Hosking family lived here until 1876, and Henry Moore moved in with his family in 1879. The New South Wales government bought the site in 1914–15 under the Foreshores Resumption Scheme, and from 1915 to 1933 it was the Strickland Convalescent Home for Women.

The house shows how 19th-century architecture in New South Wales blended Victorian design with local sandstone building methods. This combination was typical of wealthy coastal homes during that era.

The house stands at 52 Vaucluse Road, with the grassed slope and path in front of the white facade and its four-column portico. The site is owned by the Government of New South Wales and has been used as an urban park since 1990, so visitors walk the grounds rather than the rooms. The land falls toward the harbour and the remnants of a sandstone wharf near Milk Beach.

The house preserves its original harbor views and grounds from the 1850s, making it one of few intact Victorian estates in Sydney. This continuity is rare, as many neighboring properties have been altered or redeveloped.
